Abstract

As coherent detection is employed in polarization division multiplexing coherent optical orthogonal frequency division multiplexing (PDM-CO-OFDM) system, it is important to investigate and compensate the optical phase impact on system performance. We have presented the study on the electronic pilot-aided phase compensator (PC) at receiver to compensate phase drift due to laser linewidth for 100Gb/s PDM-CO-OFDM without optical dispersion compensation in this paper. Simulating results are shown that PC is very effective and the improvement of Q is >5dB for the typical optical transport systems of 800km link with linewidth equal to 100kHz.
